EQI Guide Note: This master specification section is written following the recommendations of
the Construction Specifications Canada (CSC) Manual of Practice, including the most
current versions of MasterFormat™, SectionFormat™ and PageFormat™. Optional text is
indicated by brackets [ ]; delete optional text in the final copy of the project specification. EQI
Guide Notes precede, or immediately follow specification text; delete the notes in the final copy
of project specification.
EQI Guide Note: Revise the section number and title to suit project requirements, specification
practices and section content. Refer to CSC MasterFormat for other section numbers and
titles that may be suitable for the project. Section numbers that are referenced in this Section,
match the numbers and titles found in the most current version of MasterFormat.
EQI Guide Note: This specification section is based primarily on the requirements of CAN/ULC
S716 Series, the EIFS Quality Assurance Program Inc., (EQI) and the EIFS QAP Manual
Document # P200-01. An EIFS wall cladding satisfying the requirements of S716 Series is
comprised of rigid insulation boards attached primarily to the substrate with adhesive, and
covered with a lamina consisting of reinforcing mesh embedded in a base coat on the
insulation board and covered with a finish coat. The EIFS is used in combination with a Water
Resistive Barrier (WRB) and a drained air space, typically achieved through the use of
geometrically shaped or grooved EPS or vertical ribbons/channels of adhesive, or a
combination of the two.

PROJECT AMBIENT CONDITIONS
EQI Guide Note: Weather conditions affect application and drying time. Hot and/or dry
conditions limit working time and accelerate drying that may require adjustments in the
scheduling of work to achieve desired results; cool and/or damp conditions extend working time
and retard drying and may require added measures for protection against wind, dust, dirt, rain
and freezing.
Installation Location: Maintain ambient and substrate surface temperatures above 4
degrees C for 24 hours before application. After application maintain ambient at
required minimum temperature to insure applied material’s surface temperatures is
sustained at a minimum 4 degrees C until fully dry in accordance with EIFS
manufacturer’s published recommendations.
EQI Guide Note: If outside weather conditions prevent application, covering and space heating
may be utilized to maintain the substrate at 4°C. Once the insulation is installed the adhesive
will be insulated from the exterior, and may drop below 4°C despite exterior temporary heating.
In these situations, the interior temperature of the facility must also be maintained above 4°C.
Once EIFS materials have dried, heating is no longer required. Further, maintaining a wet
material’s surface temperature at 4 degrees C will require an increase in ambient
temperatures from the minimum 4 degrees C until majority of water has evaporated. Curing
will require no less than 4 degrees C, or higher for the period of time specified by the
manufacturer.
.2
Cover and heat space surrounding application area as required to maintain minimum
project ambient, surface and material temperature conditions.
.1
Ensure surface temperature of applied materials remains above 4°C.
EQI Guide Note: Heating of the covered space may increase the moisture content of the air,
which in turn may affect the drying time of the base coat, finish coat or the complete lamina.
This is particularly evident when heating by direct fired propane, or natural gas, which produces
water vapour as a by-product of combustion. Indirect forced air heaters are preferable.
.2
Ensure adequate ventilation of covered space.
